Add DEBUG_PROXY directive around all log_dbg_level_printf() and related lines
Log stats to syslog, similar to error logs, so that it is simpler to rotate and parse
-O w/o -g is failing bufferevent_socket_connect for parent dst, so either enable -O w/ -g, or disable -O w/o -g (-O2 is failing too)
Refactoring
- Update copyright to 2015
- Remove the non-standard "unmodified" from the 2-clause BSD license
- Remove scalable from the tagline to avoid misinterpretations
Make -w and -W work in conjunction with dropping privileges and
chrooting by moving the cert writer code to a separate logger thread and
using the privsep framework to open the files if they do not exist
already.
Issue: #70
Fork into a monitor parent process and an actual proxy child process,
communicating over AF_UNIX sockets. Certain privileged operations are
performed through the privileged parent process, like opening log files
or listener sockets, while all other operations happen in the child
process, which can now drop its privileges without side-effects for
log file opening and other privileged operations. This is also a
preparation for -l/-L logfile reopening through SIGUSR1.
This means that -S and -F are no longer relative to chroot() if used
with -j. This is a deliberate POLA violation.
